Features of a Good Flashlight From time in memorial, there are instances that call for use of portable light. Even though people commonly use headlamps, flashlights are applicable in several circumstances. The later provides a strong beam light that is portable. Flashlights are also ideal when one sets out for a task that requires controlled light. On top of that, flashlights are ideal for sending a light signal. Whilst LED flashlights are small, light and bright, there are several factors that one should consider when shopping for a flashlight as this article discusses. Light Capacity Lumens are the units for measuring the light emission of a flash. The best time to apply the units is when the light uses new batteries as its source of power. Light settings are also a factor to consider during the light output measurement process. There are various levels of light output, and they range from one that is used by book readers to one that terrain travelers use. Beam Distance Meters are used for identifying the beam distance. This feature represents the flash brightness length before it fuses with the moonlight. As a common element, a full moonlight is enough for a careful and safe outdoor travel. When one intends to measure the beam distance, they should consider the brightness settings of the flash. Time take for One Run Run time denotes the time taken by a flash for its brightness to fall to a stipulated level. There are two types of run times: time take for a gradual decrease and time taken for a constant brightness with a sudden decrease. Each light setting has its own run time, and it is possible to draw a graph that defines the run time performance of a flash.

Impact Resistance An accident fall on the ground of a flashlight calls for an assessment of its resistance to an impact. The assessment of the impact resistance of a flash involves dropping the flash on the ground for a number of times. Importantly, the test does not resemble the one for assessing the resistance of an impact of a flash after its hits against object or a vehicle runs over it. This test is only meant to test the functionality of a flash on an instance where it falls on the ground from a high height.

Resistance to water Sometimes a need arises where one is required to use a flash around water bodies or during a rainy day. This consideration necessitates the flash to be waterproof. Water resistance is measured using IPX system. This unit applies when a flash encounters splash from all angles, submerses in water or immerses on water. Additional Features The bulb type of a flash determines whether it uses LED technology or normal bulbs A flash can also have a spot, flood or adjustable beam type. As the last factor, one should also consider the output of the flash, battery type, materials and shape; modes, controls, accessories, shape and size; and weight and materials of a flashlight.
